As I see it, the importance of each document could be arranged like this:

CFD 200 Modules 3-7

SAN Design Best Practices

FOS Administrator’s Guide

The rest.

With 1/2 sharing the top spot. I haven’t gone through the modules yet but I presume they all complement each other.
The reason for them sharing the top spot is because for this Beta Exam, the CFD200 material is for 8Gbps (and it has quite a lot of details about the M-series McData switches, which the 16Gbps BCFD did not include).

There is also a Knowledge Assessment on my.brocade.com ‘education’ page.
It’s called “CFD 201 8 Gbit/sec BCFD Knowledge Assessment”. Again, this is for 8G so beware that some stuff may not be up to date if you are doing the Beta for BCFD 16G. But, the actual type of questions is something that is useful. It mentions EFCM or Fabric Manager some times (this is the previous names of DCFM or what’s now called Brocade Network Advisor).

There is a nutshell guide for BCFD, but this is from November 2008 making it possibly even more outdated than the CFD200 material. But, because most of the topics are still valid it would still work as a refresher, but you can’t use it for anything specific.

I am doubtful that the M-series will be included in the BCFD 16G exam but as it’s still in the objectives for the 8G it’s probably wise to not skip that part completely. For that 1.5 years (half 2009 and 2010) when I did SAN support I only had one call about a McData switch.

FX8-24 has support for all features above, except: Jumbo frames (only FR4-18i supports those), IPv6 addresses for FCIP tunnels or IPsec, or 3rd WAN optimization hardware (the other do support this pre FOS 7)

Monitoring and Diagnostic Testing in Today’s High Speed High Density Networks

“You can run the agshow command to display Access Gateway information registered with the fabric. When an Access Gateway is exclusively connected to non-Fabric-OS-based switches, it will not show up in the agshow output on other Brocade switches in the fabric.”
